GLORY DAY ~That Shining Day~ (Japanese: GLORY DAY 〜輝くその日〜GLORY DAY ~Kagayaku Sono Hi~) was the fifth ending theme song of the Japanese Advanced GenerationPokémon anime series, and the 18th ending overall.

The animation for GLORY DAY contains the most complex animation seen in any Pokémon ending sequence: it features animated images on top of a moving sky background. Included are scenes of all the current major characters, their Pokémon, and all of Ash's past Pokémon. The new animation (used from AG150 to AG172) featured Ash and Pikachu walking on a side of the screen as clips from the current episode were being played on the left side.

The POWER MIX, most likely the version used for the television ending, is only slightly different from the original mix. It features an organ at the beginning and brass instead of synthesizer during the final bridge.

May's Pokémon appear with her, followed by Ash's (who is, weirdly, carrying Torkoal). Snorunt/Glalie then bounces across the screen. Brock and Max are shown with their Pokémon, with Ludicolo dancing around. Team Rocket then appears on the screen, all in the balloon, except Jessie, who is holding a rose.

More clips follow.
Jessie, first in a Jessilina costume, then as a nurse with Dustox, then as a cheerleader with Seviper;
James, first standing on a cliff, then in a Moltres costume, then holding a rose;
Meowth, Wobbuffet, and Chimecho, disguised as May, Max, and Caroline, respectively;
Professor Oak, Tracey Sketchit, and Delia Ketchum;
